F1 => Select target...F2 => BuildF3 => Build and RunCTRL-F3 => Run (without building)
Does he want to open the target dialog, or does he want to select a speciffic target?Maybe this can be solved with some scripting. Does the key binder plugin supports only calling a script?
Currently you cannot bind a permanent key to the Select target menu item because its sub menus disappear when CB is closed and it has no sub menus to bind to when CB is opened.That menu item is actually just a place holder for a list dialog. I doubt that wxWidgets will ever have the ability to accept a key binding to such a transient object.
